[0015] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0016] This utility model discloses an easy-to-disassemble and assemble integrated charge-discharge equalization machine, combined with... Figures 1 to 4 As shown, it includes a base plate 1, a front shell 2, a back plate 3, an upper shell 4, an integrated circuit board 5, and a heat sink 6. The front shell 2 and the back plate 3 are respectively fixed to the front and rear sides of the base plate 1. The integrated circuit board 5 is fixed to the top of the heat sink 6. The bottom of the heat sink 6 is fixedly connected to the base plate 1 by screws. The upper shell 4 is inverted U-shaped and covers the base plate 1, the integrated circuit board 5, and the heat sink 6. The edge of the upper shell 4 is fixedly connected to the front shell 2, the back plate 3, and the base plate 1 by screws.

[0017] In the above structure, the base plate 1 serves as the base, and the bottom of the heat sink 6 is fixed to the base plate 1 with screws. The upper shell 4 is inverted U-shaped and inverted onto the base plate 1. The integrated circuit board 5 and the heat sink 6 are placed inside the upper shell 4. During disassembly, first remove the screws between the upper shell 4 and the base plate 1, front shell 2, and back plate 3. Then remove the screws at the bottom of the heat sink 6 to separate it from the base plate 1. Disconnect the terminal wires to remove the heat sink 6 and the integrated circuit board 5 together. After maintenance, the heat sink 6 can be fixed back to the base plate 1 with screws, and then the upper shell 4 can be installed and secured. Compared to existing disassembly methods, this invention facilitates the disassembly and assembly of the casing and allows for quick removal of the heat sink 6 and the integrated circuit board 5, effectively improving maintenance efficiency.

[0018] Regarding the preferred fixing method between the integrated circuit board 5 and the heat sink 6, in this embodiment, the integrated circuit board 5 is fixedly connected to the top of the heat sink 6 by an isolation post. The isolation post serves both to support and fix the integrated circuit board 5, and to electrically isolate the integrated circuit board 5 from the heat sink 6.

[0019] For reinforcement purposes, please refer to Figure 3 In this embodiment, two connecting blocks 50 are fixed to the front end of the integrated circuit board 5. Each connecting block 50 has a first threaded hole 51, and the front housing 2 has two first screw holes 20. The first screw holes 20 and the first threaded holes 51 are aligned one-to-one, and screws passing through the first screw holes 20 are screwed into the first threaded holes 51. The connecting blocks 50 can be directly soldered to the front end of the integrated circuit board 5. The front side of the connecting blocks 50 is tapped to form the first threaded holes 51, thus facilitating the use of screws to fix the connecting blocks 50 to the front housing 2.

[0020] As a preferred method, please refer to Figure 4 The bottom of the heat sink 6 has multiple second threaded holes 60, and the base plate 1 has multiple second screw holes 10. The second screw holes 10 are aligned with the second threaded holes 60, and screws passing through the second screw holes 10 are screwed into the second threaded holes 60. During disassembly, the integrated assembly consisting of the heat sink 6 and the integrated circuit board 5 can be disassembled by simply removing the screws on the base plate 1, making the disassembly and assembly process more convenient.

[0021] To facilitate the fixed connection of the upper shell 4 to the bottom plate 1, the front shell 2, and the back plate 3, please refer to [link / reference needed]. Figure 2In this embodiment, the left and right sides of the bottom plate 1 are respectively formed with upward bending first bending portions 11, the left and right sides of the front shell 2 are respectively formed with backward bending second bending portions 21, the left and right sides of the back plate 3 are respectively formed with forward bending third bending portions 30, and the upper shell 4 is fixedly connected to the first bending portions 11, the second bending portions 21 and the third bending portions 30 by screws.

[0022] In practical applications, this invention involves tapping threads at both the top and bottom of the heat sink, locking an isolation post at one of the tapped ends, and then fixing the isolation post to the integrated circuit board with screws to form a single assembly. Simultaneously, holes are drilled in the machine's base plate, which is connected to the tapped end of the heat sink with screws. When the integrated circuit board needs maintenance, the machine's top cover is first opened, the two PCB board fixing screws on the front cover are removed, then the heat sink fixing screws on the base plate are removed, the terminal wires are disconnected, and the integrated circuit board assembly is removed. After the circuit board maintenance is completed, it is reassembled as before. Compared to existing technologies, this invention eliminates the cumbersome disassembly and assembly of metal parts and wires in traditional structures, greatly improving work efficiency and avoiding secondary damage to the circuit board.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
